50 GPD Reverse Osmosis Membrane -NSF Certificated (1)

I have been using this product for about 2 years or more no problems

Great product

Cumple su funcion

edit: after additional hours of usage the membrane seems to have reached its stable level of rejection just under 97%. Good enough. Previously was 3 stars: It is doing okay for the price. Hopefully it will get better with another hour or two of use. After an hour of near continuous operation It is running at about 91.4% rejection. That's pretty bad. (I flushed the membrane for about 30 seconds before I started and for about 15 seconds about every 10-15 minutes during that hour of operation). As a point of comparison, swapping to a slightly older membrane, also an inexpensive 50 gpd, is rejecting at 97.7%. I used a TDS meter to measure incoming TDS of 175, outgoing of 15-16 from the Geekpure 50gpd and 4 from my older membrane.

I bought this to replace a Pure-Flo membrane that had reached the end of its usefulness. I'm convinced the original membrane, also rated at 50 GPD was in fact 25 GPD. I'm filtering water almost twice as quickly at about 8 ppm. That's pretty impressive, if you ask me. Way better than the original membrane. Also, now the pipes don't hum and squeal like they used to with the old membrane.

This was cheaper than the one I usually get and it's exactly the same RO membrane, same size

This membrane fit my reverse osmosis system perfectly. After flushing out the membrane, I tested the TDS in my water, and it read 0.03. Great product!

Great seller fast shipping

Works great

Entrega mas rápido, es bueno precio.

ottimo

No sabía que había que cambiar esta pieza, pero es facil cambiarla y mantener la osmosis en casa a punto, lo seguiré comprando. Compatible con mi Genius

Main membrane filters are a pain to install, especially when attempting to open large screw cap on the housing. Product gives good water (17 PPM when pre and post filters were changed also).
